Toallwham it may concern" Bait known that I, a citizen of-the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Elastic V ehicle- Tire's, of which the following is a specification. Y My invention'relates to improvements in J'elastic vehicle. tires, the primary object of to provide a generally, improved elastic tire which will be exceedingly simple in construction, cheap of manufactui'e, jefiic'ient in use, and presenting an improved form of tread. designed to provide increased resiliency,- and a larger road traction surface adapted to revcnt skidding, and'the sinking and burying of. the. tire in The invention consists primarily in a solid rubber or elastic tire body having symmetrical laterally-extending and projecting tread portions forming an intermediate circumferextending tread portions being capable of eflection laterally and toward the rim of the Wheel, thereby producing tensionstrains in the tread and the tire. The tire body is preferably-made up of two elastic rubber ring members as a convenient-method of manufacturing and assembling and providin the additional ad.- vantage of the ready substitution of a new ring member in case of a serious injury to one of the elastic ring members.

'With the above mentioned ends in view, the invention [consists in the novel construction, arrangement, and combination of-parts, hereinafter described, illustrated in one of its embodiments in the accompanying drawings, and particularly pointed out in the ap- .pended claims. Referring to the drawings, forming a part Figural is a 'perspec tiveview of a, section of the im roved tire applied 'to'a vehicle wheel of t e clencher type. Fig. 2, a similar view of the same, de-

Similar numerals of reference designate like parts throughout all the figures of the the present instance,

Theim'proved tire, in

vantages of myin- 1. An elastic vehicle tire, comprisinig a tire body terminating in laterally exften tapered tread portions terminating in rela* tively thin tread wings the sides of said tire body.

2. An elastic vehicle tire, comprisinglaterally extending tapered tread portions having their tread. and lateral surfaces bounded -by convex and concave contour -lines,-respectively.

projecting beyond 3. An elastic vehicle tire, comprising a;

solid-elastic r bbei' tire having-two symmetrical latera 1y extending and projecting tread portions separated by a circumfer- 'ential groove saidtread portions beingv r0 vided with diverging convex tread sur aces and concave lateral surfaces.

' 4. Ina tire, the-combination with'a. wheel telly and a clencher rim; of two elastic rubber ring members terminating in convex tread portions separated by a--c1rcumferential" groove, and transversely" disposed clamping bolts passing through and binding said ring members together.

5. In a tire, a wheel 'feily carrying a clencher rim, elastic ring members mounted of said clenche'r rim; .sind bolts in said rim and brovided with laterally ex:- tending tread portions forming :an intermediate circumferential groove, ,ciamping signature, in presence of two witnesses.
